Submitted in response to written requests from the Inquiry, usually providing lists of questions to be answered. In most cases these formed the basis of questioning in public sessions, but in some cases they were read into the record (or taken as read) and the witness did not appear in person.
Given by witnesses invited by the Inquiry, normally after they have made written statements. These sessions could be viewed live online and sometimes on television news services, and the video recordings are part of the archive. The statements were usually released to the public after the public sessions.
As well as individual evidence, Alan Rusbridger, editor at the time of the Inquiry, and other Guardian staff gave submissions on plurality of the press. A Core Participant in the Inquiry, GNM was in addition asked by the Inquiry to identify five recently published investigations which it considered to be particularly illustrative both of the value of public-interest journalism and the difficulties it can face. GNM told the Inquiry that any new system of press regulation had to consider the impact of ownership and plurality, arguing that regulation which allowed the continuing concentration of ownership in the hands of billionaire proprietors would impoverish society.
